Heart Cake Tutorial {Surprise Inside Cake}

Finally!! Is that what you are thinking? Its ok. You can admit it. We are all friends here.

Do you remember this little thing?

Pin It

Well it turns out some of you daring bakers want to make this Surprise Inside Cake yourselves. Yeah you! I cant wait to see and read all about it… send me links girls! (and boys… if there are any boys)

Well. In order for me to do a tutorial I had to make another one. So, forgive the less then stellar decorations, but here is our ‘tutorial’ heart cake.

IMG_7699.cake

But you didnt come to see the outside right?

Here goes.

Start out by making four eight inch pans of white cake. (If you want the actual recipe, just click here)

Make one 9×13 (you can do whatever shape and size you want) pan of red velvet cake. (recipe here)

First I need to level each cake.

I use this handy dandy leveling cake thingy I got at Walmart for a few bucks.

Remember to do this for all four white cakes.

IMG_7624.cake

Add about 1/2 cup to 1 cup frosting and then put one layer on top. You want two separate two layer cakes at this point.

IMG_7626.cake

For the red velvet cake I just ran my fork through it to break it up. Then I added about a cup of frosting and combined well.

NOW! I usually like to freeze the cakes for at least a couple hours. If you cant freeze them, at least try and pop them in the fridge for a bit!

IMG_7630.toothpick
I know this looks pretty weird (maybe cause it is) but this is what I am going to use to make sure I have some uniformity in the heart design. Its just two toothpicks and a piece of twine.

IMG_7632.cake
Place one toothpick in the center of the cake, then (holding firmly) drag the outside toothpick around the cake and make a circle.

IMG_7635.cake
Like this! Now I have a rough guide line of where I am going to being carving. Do this to both cakes. (or, if you are a good drawer, just take a knife and cut a shallow line around the perimeter.)

IMG_7646.cake

Carve out a V shape in the cake.

IMG_7651.cakecollage

The top half of the heart is a little trickier. This time, I started with my knife in the center of the cake and created this little island.

I then moved back out to my “guide line” and started cutting. I ended up creating this channel. Once this has been created, you can go back in a do some more carving to create more detail.

IMG_7658.cake

Here is after I went in with a spoon and carved out a bit more.

IMG_7654.cakes
The two cakes carved out. The hard part is pretty much done now!

IMG_7666.cakes

Now I can start filling in the cakes with the red velvet cake.

IMG_7677.cake

All filled! At this point I put it in my freezer for about 15 minutes. Just to let them set.

IMG_7680.cake

I added some frosting the the edge of the bottom cake. Make sure you know which is which! You are going to want to add the cake with the hallowed out ‘channel’ to the top of the V cake.

IMG_7683.cake

Here goes nothin! I have found the easiest way to do this is to just use your hand. Place it flat over the top of the ‘channel’ cake and flip it over. Then gently place it one the bottom cake.

IMG_7685.cake

Add some more frosting and do a rough crumb coat over the whole cake.

IMG_7689.cake

And here is our thin layer of icing for the crumb coat. Put this in the fridge about at least a half hour, or as long as overnight.

Now. Go eat an apple. Seriously. Cause if you are anything like me you have been snacking on the cake scraps this whole time and you need a healthy energy boost.

There. Feel better? Lets get back to work.

IMG_7699.cake

I ended up using all my red velvet cake so I didnt have any left over for decoration. So white it is!

Ready to see what all this work was for?

IMG_7755.heartcake

I thought it turned out pretty good! Granted, this is my third time making it in a month so I had better be able to at least make it presentable by now. :)

IMG_7765.sliceofcake

IMG_7749.heartcake

And it tastes as good as it looks! (I might be biased)

So I hope you are brave enough to try a heart cake for your loved one this Valentines Day. Be sure to let me know how it works out.. and take lots and lots of pictures! :)

Recipes:

Red Velvet Cake

For the red velvet cake I messed around with a recipe from Magnolia Bakery.

*This is how I modified this recipe: I used 2 sticks of butter, 2 eggs and 2 egg yolks, 2 tablespoons of food color, and apple cider vinegar. I wanted a more dense cake because I knew I was using it in the center of the heart cake and I needed to make sure it was sturdy enough.

3 1/3 cups cake flour (not self-rising)
3/4 cup (1 1/2 sticks) unsalted butter, softened
2 1/4 cups sugar
3 large eggs, at room temperature
6 tablespoons red food coloring
3 tablespoons unsweetened cocoa
1 1/2 teaspoons vanilla extract
1 1/2 teaspoons salt
1 1/2 cups buttermilk
1 1/2 teaspoons cider vinegar
1 1/2 teaspoons baking soda

Directions

Preheat oven to 350 degrees.

Grease and lightly flour three 9 x 2-inch round cake pans, then line the bottoms with waxed paper.

To make the cake:
In a small bowl, sift the cake flour and set aside. In a large bowl, on the medium speed of an electric mixer, cream the butter and sugar until very light and fluffy, about 5 minutes. Add the eggs, one at a time, beating well after each addition.

In a small bowl, whisk together the red food coloring, cocoa, and vanilla. Add to the batter and beat well.

In a measuring cup, stir the salt into the buttermilk. Add to the batter in three parts, alternating with the flour. With each addition, beat until the ingredients are incorporated, but do not overbeat.

In a small bowl, stir together the cider vinegar and baking soda. Add to the batter and mix well. Using a rubber spatula, scrape down the batter in the bowl, making sure the ingredients are well blended and the batter is smooth.

Divide the batter among the prepared pans. Bake for 30-40 minutes, or until a cake tester inserted in the center of the cake comes out clean. Let the layers cool in the pans for 1 hour. Remove from the pans and cool completely on a wire rack.

*****

*I used only all-purpose flour and then added 1 tsp baking powder. I am going to play around with this a bit more next time and maybe even add some baking soda. I found this recipe on Food Network.

White Cake

  • 1 1/2 cups self-rising flour
  • 1 1/4 cups all-purpose flour
  • 1 cup (2 sticks) unsalted butter, softened
  • 2 cups sugar
  • 4 large eggs, at room temperature
  • 1 cup milk
  • 1 teaspoon vanilla extract

Directions

Preheat oven to 350 degrees F.

In a small bowl, combine the flours. Set aside.

In a large bowl, on the medium speed of an electric mixer, cream the butter until smooth. Add the sugar gradually and beat until fluffy, about 3 minutes. Add the eggs, 1 at a time, beating well after each addition. Add the dry ingredients in 3 parts, alternating with the milk and vanilla. With each addition, beat until the ingredients are incorporated but do not over beat. Using a rubber spatula, scrape down the batter in the bowl to make sure the ingredients are well blended. Carefully spoon the batter into cake pan. Bake for 20 to 25 minutes (for round cake), or until a cake tester inserted into the center of the cake comes out clean.

*****

And I am loving Magnolia’s Vanilla Buttercream frosting.

*My only modification to the recipe is I like to add a little almond extract, and it seems that 1 tsp. is the perfect amount! And be sure to use CLEAR vanilla extract to get a white frosting.

Makes enough for one 2-layer 9-inch cake or 2 dozen cupcakes*

  • 1 cup (2 sticks) unsalted butter, softened

  • 6 to 8 cups confectioners’ sugar

  • 1/2 cup milk

  • 2 teaspoons vanilla extract

Place the butter in a large mixing bowl. Add 4 cups of the sugar and then the milk and vanilla. On the medium speed of an electric mixer, beat until smooth and creamy, about 3-5 minutes. Gradually add the remaining sugar, 1 cup at a time, beating well after each addition (about 2 minutes), until the icing is thick enough to be of good spreading consistency. You may not need to add all of the sugar. If desired, add a few drops of food coloring and mix thoroughly. (Use and store the icing at room temperature because icing will set if chilled.) Icing can be stored in an airtight container for up to 3 days.

    Just wondering how you made your white cake and icing so white despite it containing butter… All the white cake recipes I have tried have yielded a colour like your stock standard butter cake.

  2. Cierra says

    Will your cake recipe be enough for all four, two or just the one? thanks for the idea! Ill definitly be doing this for my boyfriends birthday that is just around the corner :)

  3. ilona says

    One question, why do you bake 4 white cakes and than cut the in half so you get 8 cakes. But if you lookat t at the cake it only has 4 layers. Cant you just bake 2 cakes and cut them in half? Or bake 4 cakes and dont cut them in half?

  4. says

    Wow, this is amazing and something I would never have thought I could do until I read your tutorial. I seriously think I want to make this! The question I have is about the red velvet cake. You said you broke it up and then added frosting? So it’s not just cake crumbs I see, it’s cake and some frosting to make it sort of a tacky balll of joy? Or am I reading something wrong?

  5. Diana says

    This cake is so cute. I love to bake and will defiently give this one a try, your step by step instructions are amazing. Thanks for the great ideas.

  6. Chevelle says

    going to try this for either Valentine’s our my one year anniversary with my boyfriend. seen this on Pintrest and i feel in love. lolol, I’m so excited to make it :)

  7. jane says

    I did it!!! Not as perfect as yours, but good for my first attempt! AND FUN!!! But my red velvet cake is darker…. not nearly as bright red!! Did you use the cocoa in the Magnolia red velvet recipe? Yours is beautiful! And you are an inspiration! Thank you! <3

    I am primarily a performer, but I love to bake. Today I had a Valentine’s Day performance and decided to combine my two loves and create this cake for the reception afterwards. I was extremely worried I didn’t execute it well enough for it to look like a heart, but your tutorial is so well made, I shouldn’t have been worried at all! The cake worked beautifully and was perfect for the theme of the performance. Thanks for being so creative and sharing these ideas with us!

  9. Katie says

    How do you get the buttercream so white?? I use a clear vanilla extract. My frosting always comes out a little yellow/cream. Do you use a special butter?? By the way, I LOVE LOVE LOVE your blog!!!!

    Hi.

    My name is Denyse Hng and I love your website. Your creations are incredible! And the tutorials are amazingly useful.

    I was wondering if I could reprint both this recipe as well as your buttercream recipe for my Food Tech portfolio as I will be making the heart cake for my Alice in Wonderland themed folio. (I am a student in Australia and the folio is part of my final year studies). I will include the links to the recipes and credit you in my bibliography. :)

    Thank you!

    • says

      Hi Denyse- What exactly is a Food Tech portfolio? I cant give permission for you to reprint the cake and recipes in an public format…

  11. Alexis says

    Instead of using the cake recipes that you give, you it still work if I use store bought cake mix? This is a really cool cake! I’m going to try to make it for my parents anniersary! How it goes well

  12. April says

    Wonder if you can do this for a mickey mouse inside? I have been trying all day yesterday to do something like this but with a brownie paste…maybe cake is the key! The brownie paste that is molded to do the ears just keeps sinking to the bottom while I cook the cake. Going to try and come up with a cutout for the ball on the bottom and use the top of your heart for the ears but a bit more rounded…any advice?

  13. connie says

    gorgeous cake you did a wonderful job. maybe some day i will get up enough courage to try this, also there is a broken link for one of the pictures. the one where you are ready to flip the cake over and put it on top of the bottom half.

  14. says

    If you’d like to try a frosting that isn’t so sweet, here’s a recipe I found about 50 years ago in a cookbook from Rose’s Deli in New York City. I call it a French Buttercream.

    Cream together:
    1 c. (2 sticks) regular butter
    1/2 c. Hi-Ratio Shortening, like Sweetex, OR white Crisco

    Add and beat in:
    2 T. light Caro Syrup
    1 t. vanilla

    Add:
    2 c. 10X Confectionary Sugar (Domino 10x versus a generic 6x sugar)
    (If the bag has already been opened, I sift before adding)

    Whip on high speed until light and fluffy.

    Add:
    2 egg whites, or pasteurized egg whites
    (add one egg white at a time, and only beat about 30 seconds after the 2nd egg white is added)

    The frosting will take on a whole different texture.

    Refrigerate cake when frosted and decorated. Let warm up a little just before serving so the frosting isn’t hard.

    Here’s the fun part:
    For a Chocolate Frosting, add 1/2 c. sifted cocoa to the butter and shortening, and use vanilla.
    For an Orange Frosting, add 1 t. orange extract in place of the vanilla, and some freshly grated orange zest. Add some food color if you want it more orange.
    For a Lemon Frosting, add 1 t. lemon extract and some freshly grated lemon zest.

    You can make any flavor you want, by changing the extract you use – strawberry, banana, etc.

    I know there is a great deal of controversy over the use of raw egg whites. It is the philosophy of many chefs I know to use the raw egg, as long as you know your purveyor, and have confidence that their eggs are fresh, and handled correctly.

    If you have a problem with this, simply use pasteurized egg whites from your favorite store. I think most stores carry them now.

    Or you can heat raw egg whites, over a hot water bath, until they reach a temperature above 140
    degrees. Be careful to stir them and don’t let them cook.

    Thanks for sharing the recipe for the heart cake. I’ve been admiring this picture for a couple of years now and dreaming of how delicious it must be. Now I can find out for myself!

    Thanks again.

    Sincerely,

    Anne M.

    Red food coloring causes cancer. Use Beet juice to color your red velvet cake. Works great and you won’t be able to taste the beets. :-)

  17. Stephanie Stanley says

    I have a question I will be making this cake in a couple of weeks (super excited) but I have to travel with it. What would the best way to travel with this cake with the 2 halves or as one whole cake. Time of travel is approximately 4 1/2 to 5 hrs. Thank you for allowing us to see your wonderful work.

    • says

      Hi Stephanie! I would travel with your whole cake. Once you make it (assemble it), freeze it. That will ensure more stability! :)
